1. Kinematics (Stuff moving) (stuff)

2. Start with vocabulary Position – where it is Displacement – how far it moved, direction (+/-) is important Velocity – how fast it moves, direction is important (+/-) –Instantaneous, right now! Slope of tangent Average velocity – change in position divided by change in time

3. Vocabulary, continued Acceleration – rate of change in velocity –Instantaneous, Slope of velocity time curve –Average, over time interval –Our equations apply only to contsant acceleration –When acceleration changes, we break the problem into chunks of constant acceleration

4. The Equations!

5. Daddy

6. Definitions

7. Mommy Notice no time in this one!

8. One more! v t Avg velocity

9. The Equations!

10. Decipher word problems …at rest, …from rest – not moving at beginning… v 0 = zero! …Travels 10 m in 10 sec… –d f =10m,  t=10 s …reaches a maximum height – velocity at h max = zero!

11. Kinematics Examples

12. Freefall Examples Same kinematics equations… Just constant acceleration of g=9.8 m/s 2 toward mother earth.

13. Freefall Cases Downy Uppy Uppy - downy

14. Wrap up Givens Unknowns P&P E –Time or none given S & S & S

15. On site problem work More example problems from the worksheets
